How to grow sweet peas from seedSweet Pea
Sow sweet peas at a temperature of 10-15C/50-60F they don’t need high temperatures to germinate. Sow seed individually into deep pots or cell trays filled with good quality compost. Keep somewhere warm; such as in a propagator or on a warm windowsill, and keep the compost moist but not wet until seeds germinate.
When the sweet pea seedlings are growing strongly, pinch out the growing tips to encourage the plants to branch. This will give you several stems and lots of flowers.
Sweet peas are tough plants so they don’t need a warm greenhouse; once the seed has germinated a cold frame or a bright spot near a window in a shed or porch will be fine, but protect the young plants from frosts and severe weather with an extra layer of fleece if necessary. The well-rooted sweet peas can be hardened off ready to be planted outside in spring when soil warms up.
Planting out Sweet Peas
Sweet peas are hungry plants so add a special sweet pea fertiliser to the soil before you plant for the best results.
If you are growing the traditional tall sweet peas, grow them up strong supports; use trellis, sweet pea netting or wigwams made of canes or hazel. Plant the sweet peas at the base of the supports when soil warms up in spring. Our Marberry Obelisk planter is a stylish way to grow tall sweet peas on a patio or in a courtyard garden.
In milder areas sow during October or November and overwinter the young plants in cold frames or unheated glasshouse,to prevent the seedlings becoming leggy. Over winter, keep the frame opened as much as possible, but protect from heavier frosts
Support young plants with canes, netting or trellis to about 180cm (6ft). Pick the blooms regularly to ensure a continuous supply.
